Hi Marek,
Fusion handling of EDL is indeed less than stellar at the moment, Generation is generally 'better' suited for that task. That being said, it has not been tested with all formats of EDL and I would be happy to take a look at what you have, maybe I can tweak the format a bit.
As for Resolve handling the EDL better, it's not as ridiculous as you think considering we have just recently acquired Fusion and it's design was not based around EDLs in the same way as a color grading/editing application would be.
Give us some time, we have a lot of developers on it now, and I am excited about Fusion in 2015!
